Unlocked bootloader root - Xperia Z3 Q&A, Help & Troubleshooting

Hey guys I am on Android 5.1.1 which. 546 firmware.
I have unlocked bootloader now I want to root my phone and install twrp.
I need help on how to do it.
Thanks in advance

Wrong way round.... You shoukd root then unlock. That way you can take a backup of your ta partition. Now you have lost it (and your drm keys) forever.
But to get root here is just one way, just fastboot an insecure kernel, (any from a custom rom such as cm) and then flash any rooted rom. Dont forget to flash a compatible kernel to the rom you flashed afterwards. Do not boot the phone in between each step

Close it then bro @gregbradley

[Q] Keep root and recovery with locked bootloader after upgrading to Lollipop?

Hi guys,
My girlfriend has a Xperia Z3, currently not rooted, bootloader is locked, no custom recovery and running Kitkat. I'm planning on rooting her phone for her install TWRP just to make a backup of the ROM, then I will update it to Lollipop right after.
I want to keep the bootloader locked because from what I've read, unlocking bootloader wipes the DRM keys or something, which apparently affects camera and even battery life for some people. I know I can back up the TA partition but that doesn't fix the fact that the camera will be affected somehow. I just don't want to take the risk and deal with the possibility.
So how would I root and install TWRP on a locked bootloader Xperia Z3 running Lollipop? I haven't seen any topics or guides on this, most are for phones with UNLOCKED bootloader so it's not really helping...
Read the Guide in the general section for rooting a locked bootloader
http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056
You haven't researched much i see..
If you have 23.0.A.2.93 version, all you need is to Root, install TWRP, then FLASH a pre-rooted Lollipop rom.
I've read that guide already and I don't see any pre-rooted LP roms for either New Zealand or Taiwan. I know it probably won't matter, but for phones like Samsung Galaxy S5, we have CSC codes which basically gives you access to certain apps or options depending on the country of the ROM. If possible, I'd like to update to Lollipop from the official OTA and then root it from there.
Also, I'm on a newer KK firmware, which means I'll need to downgrade in order to get root. But doing that also means I lose all the contents on the phone, which I want to backup first using Titanium Backup. I understand there's a sacrifice here but I'm a bit confused as to why we couldn't just flash recovery using fastboot (like most other phones do) and then install SuperSU from TWRP? Or is the downgrade necessarily in order for us to achieve root via an unpatched exploit?
UPDATE:
Forgot to mention one major issue, my girlfriend's Z3 is D6653. The 23.0.A.2.93 firmware for D6653 is for T-MOBILE, but my girlfriend's phone is an international variant so I'm not sure it's compatible.
you know you can flash a rom with flashtool and not have it wipe the data?

Help! Sony Xperia Z3 Dual (D6633) pre-rooted

Hi all
I have searched for a long time about rooting my device, but i found nothing
I have Sony Xperia Z3 Dual (D6633) with android 5.1.1 build 23.4.A.1.232 and locked bootloader.
So, I need to root it or install a pre-rooted stock firmware without touching the bootloader.
Hi, you need to flash a kitkat rom with flashtool then root with giefroot. (I'm not sure about other rooting methods but this is the safest way IMO.)
After it got rooted, install a recovery so you can flash pre-rooted stock firmware or whatever you want. Remember to backup TA partition.
I had D6633 before and worked perfectly.
I have posted this before but you can go directly to the thread http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056

As far as I know, stock roms with stock kernel don't need bootloader to be unlocked. You need to unlock the bootloader in order to flash custom kernel and aosp stuffs.
tl;dr, if you are not gonna use custom kernel and aosp stuffs your bootloader can remain locked.
Ok, if you want to install moonbreakers, here's what I did when I first bought the device. I never unlock my bootloader.
1. Prepare the tools and root the device using Giefroot. and I recommend you to backup TA partition first just in case.
2.Install dual recovery.
3.Now that you have a working recovery you can flash any stock roms.
here's the guide by G-FACE.
if you want to unlock the bootloader remember to backup TA partition before you do it. If it's lost you can't get it back.

First of all, thanks for your help
Well i'm not professional, I only understand the rooting process.
But I have some questions:
1- can I make a ftf file as a backup from my exist firmware, so when I decide to reverse the whole process and return my device back to its original state, without losing anything?
2- What is the recovery, is that recovery has any disadvantage or negatively affect my device?
3- I didn't find a firmware 23.4.A.1.232 with the same customization version which is 1288-7361_R3C

sony z3 d6653 lolipop 23.4.A.0.546 root help

i unlocked the bootloader but theirs no way to root without downgrading to kk..
is theres a way fo rooting with this update can i have it
im new to sony and had a bricked problem yesterday
played a little bit with flash tool and managed to get out of it with the Unlocked bootloader..
And you were aware of such keywords like "camera DRM", "TA partition", "backup" before unlocking, right?
I've aswered you elsewhere too, but, the procedure is kinda universal (for Z phones that is): downgrade to KK, giefroot, XZDR, update to pre-rooted LL.
What's your issue with that? You do it once and you just flash the next version, keeping data, but wiping dalvik&cache.
i didnt keep the drm backup...
now i dont think i can restore it
it doesnt matter all i need to do it to root this and have the full power to my self
done and rooted and everything works fine..now i nned toknow if theres any pure android marshmellow available??
...
To root with an unlocked boot loader is the easiest thing, just flash an insecure kernel.
As for ROMS, head over to the development section and take a browse there.

If you flash the stock firmware with Odin you do not lose your data.
If you want to completely back to its original state, you have to make after a factory reset.
Without Factory Reset You keep your data [emoji41]

DRM key after flashing stock

Hello guys,
maybe it is a stupid question but i have unlocked my bootloader and restored TA Backup a couple of month ago. Then i flashed back full stock rom with flashtool unrooted as it is. Now i want to root and flash my e6653 again. Do i need to make a new backup and restore of my DRM Key or is it already done by making this earlier ?
Thanks guys
Im sure you dont need to make a new backup.
So can i direct Flash a custom Rom and rooted Kernel or Do i need to repack and root my Stock Kernel First?

First backup is OK. You can use this TA.img anytime.
No need to do this again. You are already BL Unlocked.
